For the opening of Major League Baseball’s 2009 season, tour the Texas Rangers’ grand Rangers Ballpark in Arlington and visit the Legends of the Game Baseball Museum and Learning Center. Upgrades to the ballpark include new scoreboards and premium home-plate seating -- just in time for home games this month against the Cleveland Indians, the Baltimore Orioles, the Kansas City Royals, and the Oakland Athletics.

Fort Worth’s Texas Motor Speedway, one of the world’s largest sports venues, offers tours of its 1,500-acre facility, which challenges America’s best race-car drivers.

Just north of downtown Dallas is the American Airlines Center, the high-tech home of the National Basketball Association’s Dallas Mavericks and the National Hockey League’s Dallas Stars. It’s also a leading venue for concerts and other major events. Tours take the public inside operations.

And the thoroughbred-horse-racing season is off and running this month at Grand Prairie’s Class 1 Lone Star Park, just miles from the airport.
